Finishing touches are being put on the recently-opened wider Interstate 10 in Baton Rouge this week, and the Louisiana Department of Transportation and Development warns that drivers should keep an eye out for lane and ramp closures.

The interstate will be reduced to one or two lanes in various places between the I-10/I-12 split and Siegen Lane at night all week through Sunday. The closures will take place from 9 p.m. to 5 a.m. on weeknights and 9:30 p.m. to 7:30 a.m. on Friday and Saturday night. At least one lane will still be open, DOTD says.

Crews will also be closing parts of Siegen on Tuesday between 9 p.m. and 5 a.m. The Siegen on- and off-ramps, as well as the two turn lanes from North Mall Drive to northbound Siegen, will be intermittently closed for about 10 minutes during the night.

Several other ramps will be closed throughout the week while crews place permanent pavement markings, remove barrier rails and grind and groove the pavement, DOTD says.

Closures include:

- The I-10 westbound exits to Siegen and Bluebonnet Boulevard will be closed Tuesday from 9 p.m. to 5 a.m.

- The on-ramp from Essen Lane to I-10 eastbound and the I-10 eastbound exit to Bluebonnet will be closed on Wednesday from 9 p.m. to 5 a.m.

- On Thursday through Saturday, various ramps will be closed. No two consecutive ramps will be closed at the same time, the DOTD says. Closures include: the I-12 eastbound on-ramp to I-10, the on-ramp from Essen to I-10W, the I-10W exit to Essen, the Bluebonnet onramp to I-10W, the I-10W exit to Bluebonnet, the on-ramp from Picardy to I-10W, and the I-10W exit to Siegen.
